Surface chemistry and spectroscopy of chromium in inorganic oxides
Article Abstract:
The surface chemistry of chromium ions in inorganic oxides exhibits variable oxidation states, coordination numbers and molecular structure. The structure and composition of inorganic oxides depend on the surface chemistry of chromium. These chromium ions are efficient catalysts for oxidation, hydrogenation-dehydrogenation and polymerization reactions. Supported chromium ions react with alcohols, ethylene and water molecules. The chemical behavior of chromium on amorphous surfaces is similar to that on molecular sieves.

Time-resolved vibrational spectroscopy of electronically excited inorganic complexes in solution
Article Abstract:
The characterization of excited states after electronic excited inorganic complexes in solution was analyzed using time-resolved resonance Raman and time-resolved infrared spectroscopies. The effect of changes in equilibrium displacement was represented by a potential energy diagram. Results showed that transient vibration spectroscopies can effectively elucidate the electronic and molecular structures associated with excited states and photochemical intermediates.

Metal oxide surfaces and their interactions with aqueous solutions and microbial organisms
Article Abstract:
The atomic-scale structure and chemical reactivity especially in aqueous environments of metal oxide surfaces have been studied. There has been an increase in scientific interest on chemical reactions at the metal oxide-aqueous solution interface due to their importance in a number of fields. The interface is reactive due to acid-base, ligand-exchange and redox chemistry involving protons, hydroxyl groups, aqueous metal ions and aqueous organic species.
